CM-SA
For quantitative evaluation & analysis of skin color and pigmentation
NEW
Simultaneous Measurement of Skin Color and Melanin Index
Used in combination with a Konica Minolta spectrophotometer, the CM-SA enables highly accurate measurement of skin color simultaneously with a numerical display of the Melanin Index, Hb (Hemoglobin) Index, and Hb SO2 (Hemoglobin oxygen saturation) Index (%).
Specifications
Major specifications of CM-SA
| Skin data display | Melanin Index Hb Index [Total hemoglobin (oxidized + reduced) index] Hb SO2 Index (%) [Hemoglobin oxygen saturation index (%)] |
|---|---|
| Colorimetric value display | L*, a*, b*, Munsell value (Hue, Value, Chroma)*1 |
| Graph display | Hue–Value Graph, Hb Index–Melanin Index Graph |
| Data handling | Saving/reading data in CM-SA original format Saving data in text (CSV) format [Melanin Index, Hb Index, Hb SO2 Index (%), L*, a*, b*, Munsell value (Hue, Value, Chroma), Spectral reflectance (400-700 nm)*2] |
*1 Munsell data are calculated for 2° observer and Standard Illuminant C.
*2 The spectral reflectance data that are output are the reflectance obtained in SCI (specular component included) mode.
